Technical Field
[0001] This utility model relates to the field of tea packaging technology, and in particular to a weighing and packaging device for Wuyi rock tea. Background Technology
[0002] Traditional tea packaging often involves manual weighing and bagging, which is inefficient and prone to contamination. To facilitate tea storage and sales, packaging is necessary, requiring the use of tea packaging equipment. Utility model patent application CN201520515946.1 discloses tea packaging equipment. Existing tea packaging equipment generally offers advantages such as fast packaging speed, good sealing, low energy consumption, ease of operation, and long service life, meeting the needs of tea packaging. However, existing tea packaging equipment has several drawbacks. First, before packaging, personnel need to weigh the tea, increasing labor costs. Second, during weighing, it is often difficult to accurately control the weight of the added tea, requiring repeated additions and removals, reducing packaging efficiency. Existing automated equipment also suffers from the following problems: weighing accuracy is affected by vibration, leading to errors; and different packaging sizes require frequent adjustments to equipment parameters.

[0011] The present invention will be further described below with reference to the accompanying drawings.
[0012] Please see Figure 1 and Figure 2 As shown, this utility model provides an embodiment: a weighing and packaging device for Wuyi rock tea, including a support frame 1, a weighing chamber 2 mounted on the support frame 1, a feeding component 3 embedded on the upper surface of the weighing chamber 2, support blocks 21 mounted on the bottom of the left and right sides of the weighing chamber 2, a weighing sensor 22 mounted on the upper surface of the support block 21, a first telescopic rod 23 mounted on the upper surface of the weighing sensor 22, a first return spring 24 sleeved on the first telescopic rod 23, a weighing block 25 mounted at the end of the first telescopic rod 24, and a receiving plate 26 rotatably mounted on the inner side of the weighing block 25 via a rotating shaft; a discharging component 4 is connected to the lower surface of the weighing chamber 2. The tea leaves are fed onto the receiving plate 26 via the feeding component 3, and then weighed by the weighing sensor 22 to determine the weight of the tea leaves. A motor drives the receiving plate 26 to swing up and down, enabling the opening and closing of the receiving plate 26, thereby achieving the discharging and packaging of tea leaves of the corresponding weight.
